STMicroelectronics SMBJ15A-TR Transient Voltage Suppressor

The SMBJ15A-TR from STMicroelectronics is a robust transient voltage suppressor (TVS) designed to protect sensitive electronics from voltage spikes and surges. This device is part of the SMBJ series, which is known for its high reliability and performance in surge protection. The SMBJ15A-TR is particularly suitable for applications that require a stand-off voltage of 15V, making it an ideal choice for a wide range of industrial, computing, and consumer electronics applications.

Constructed with high-quality materials, the SMBJ15A-TR offers a peak pulse power dissipation of 600W (10/1000μs waveform), which ensures that your electronic components are shielded from transient events such as electrostatic discharges (ESD), electrical fast transients (EFT), and secondary lightning effects. The device's bidirectional clamping action provides symmetrical protection, which is essential for alternating current (AC) applications or where the polarity of the transient could be either positive or negative.

Featuring a fast response time, the SMBJ15A-TR reacts quickly to surge events, minimizing the risk of damage to the protected component. Its low incremental surge resistance ensures that the device remains effective even under high surge conditions. The TVS comes in a compact DO-214AA package, also known as an SMB package, which is suitable for automated assembly and offers good thermal and electrical characteristics.

The SMBJ15A-TR is also characterized by its low leakage current and excellent clamping capability. The 15V stand-off voltage is precisely controlled to ensure consistent performance. Additionally, the device meets the IEC 61000-4-2 standard for ESD, IEC 61000-4-4 for EFT, and IEC 61000-4-5 for surge immunity, making it a reliable choice for protecting sensitive circuits against the toughest transient threats.

Whether you're designing power supplies, data lines, or other sensitive circuits, the SMBJ15A-TR from STMicroelectronics provides the protection you need to maintain the integrity and longevity of your products. With its optimal combination of features, this TVS diode is an essential component for any application requiring robust surge protection.
